SAMPLE CARD Filed April 7, 1953 INVENTOR @drzqy fiender ATTORNEY Patented Got. 16, 1934 -UNITED STATES PATENT OFFICE This invention relates to sample cards in general, and particularlyto those in which the samples are intended to be observed in either single I or manifold layers, or in which the samples may be lookedt'hr'ough, and to the method of efiectively producing such' sample cards.

In samples of fine textile material, as for instance that used in ladies hosiery, it is required that the coloring of the material be readily dis- 5 tinguishable, since the shades are so delicately graduated, that the differences in colors can only be observed when the material is placed in at least two layers above one another. The present invention is intended to effectively produce sample cards of this kind, in which the material from which individual samples are to be made, is prepared in large sheets, supported by carriers, so as to facilitate the handling of the samples, without wrinlding their material, which remains stretched, thereby permitting their ready application between the cover sheets of a sample card.

I preferably proceed by first producing a suitable carrier from a sheet of fairly stiff material, V provided with an adhesive coating at both of its faces. This carrier is uniformly perforated, and to each of its gummed faces is secured a sheet of sample material. Then the material-covered backing or carrier is cut into uniform pieces, the centres of which are formed by the perforations. Now these sample pieces are ready to be placed between prepared sample card covers. The latter I are also equipped with perforations, which are smaller than those of the samples, and the inner faces of the covers are preferably coated with an adhesive. The samples are placed between two covers, so that the carrier perforations register with the perforations of the cover sheets. This assembly is now passed between hot rollers, whereby the adhesive is caused to stick the covers together; at the same time the samples are fixed in their proper position.

The prime objects of my invention are to provide a simple, eifective and inexpensive method, whereby sample cards of this kind may be uniformly produced, whereby such sample cards acquire a neat appearance, and whereby the sample material is kept stretched during the manufacture and in the finished sample cards.

Another object of my invention is to provide sample cards for material intended to be observed in one or more layers, or for material through which light is to be passed, in which the sample pieces may be uniformly produced in quantities in an inexpensive and effective Way, and whereby the wrinkling or shifting of the samplematerial is effectively prevented.

The foregoing and further objectsjwill become more fully apparent from the following description, in connection with theaccompanying drawing, forming part of 'my disclosure, but by no means intended to limit me to the actual showing, and in which Figure 1 is a partial plan view of a carrier or backing, to which a sample material is secured (.65 at both of its faces.

Figure 2 is a cross-sectional view, taken on line 22 of Figure 1.

Figure 3 is a partial plan view of a finished sample card. 1170 Figure 4 is a cross-sectional view taken on line 4-4 of Figure 2, and

Figures 5 and 6 illustrate partial plan views of other forms of carriers.

Referring now to the figures, numeral 10 de- 7 notes a carrier sheet, which is preferably provided with octagonal perforations 11, arranged in uniform rows. The carrier material is preferably gummed at both faces, to which faces are secured two or more layers of sample material, indicated at 12, in such a way that the material completely covers perforations 11. Now the material-equipped carrier is cut into uniform pieces along the broken lines, indicated at 13. A number of carriers with different materials attached 6'5 thereto are prepared. Now the cover sheets are fabricated, in that two sheets of material 14, which are preferably provided with an adhesive at their inner faces, are provided with perforations 15. These perforationsare made simultaneously through the two cover sheets, so that the openings register with one another.

In Figure 3 I have shown circular perforations, but it is quite obvious that any other shape of perforations may be provided. The sample pieces cut from the material-covered carrier are then placed between the cover sheets, so that the perforations of the carrier pieces register with the perforations of the sample card covers. This may be clearly seen from Figure 3. After proper- 3100 1y placing the sample pieces between the cover sheets, the covers are passed through heated rollers, whereby the adhesive on the inner faces of the cover sheets is caused to glue the sheets together, while at the same time fixing the sample pieces in their respective places.

In Figures 3 and 4 the individual sample pieces are indicated at 16, and their relationship in respect to the cover sheets is clearly discernabl Before gluing the cover sheets together, I

preferably provide at one edge of the sheets an attaching flap, indicated at 17, which extends beyond the edge of the sample card, for the purpose of securing it in a loose leaf book or otherwise.

In Figure 5 I have illustrated another backing or carrier 18, provided with hexagonal perforations 19, and in Figure 6 there is shown a carrier 20 with square perforations 21; In Figures -1 to 4 there is illustrated a carrier with one sheet of sample material at each face thereof. It is quite obvious, however, that more than one sheet may be secured to each face of the carrier, or that only one sheet may be affixed to one face of the carrier, in the event that only the transparency of the material is of prime importance.

In the figures I have illustrated'material intended to indicate textile. It is, however, quite evident that any other material may be thus prepared into samples for sample cards of'this "kind. It is quite obvious that various changes vice, without departing from the spirit and scope I of my invention, as set forth in the annexed claims.

I claim:

1. The method of producing sample cards for materials intended to be observed in manifold layers, which consists of attaching layers of the sample material to each surface of a perforated carrier, and securing the covered carrier between two perforated sample cardcovers so that the perforation of the carrier registers with the corresponding perforations of the covers.

2. The method of producing sample cards for materials intended to be observed in manifold layers, which consists of gumming both faces of a perforated carrier for the sample material, securing sample material in sheet form to the gummed faces of the carrier so as to completely cover the perforation, placing a prepared sample carrier between the inner, gummed faces of two uniformly, perforated covers, the perforations of which are smaller than that of the carrier, so

that the perforation of the carrier registers with the perforations of the covers, and pressing the covers together under the influence of heat,

.. thereby causing their. gummed inner faces; to

firmly connect with one another, and to fix the sample carrier in its desired position.
